provide a supporting and bracing means so constructed as to greatly add to the strength of the pole and prevent breakage of the pole supporting arch which breakage is" most likely to occur at the lateral bends in the arch.

In the accompanying drawings,

Figure 1 is a top plan view of the device embodying the present invention, and

Fig. 2 is a side elevation thereof. 7

In the drawings, the numeral 1 indicates the pole proper which, at its rear end, is

turned downwardly as at 2 and terminates at the forward side of the pole supporting arch. The said arch is indicated by the numeral 3 and as usual, is made from wood and has its end portions curved as at 4 to extend rearwardly as at 5, the arch being dis posed as usual in a forwardly and upwardly inclined plane. The usual T-iron 6 is secured to the upper side of the arch at the front thereof and to the upper side of the downwardly extending portion 2 of the pole and serves to rigidly connect the pole with the arch. The numeral 7 indicates the usual arch irons secured to the portions 5 of the said arch and extending forwardly in converging relation and secured at their forward ends to the pole 1 in advance ofthe portion 2 thereof. These irons, of course, serve to brace the pole against lateral displacement with relation to the arch and at their rear ends, the said irons project beyond the extremities of the portions 5 of the arch and are provided with the usual members 8 for connection with the-thill couplings of the vehicle. The usual doubletree 9 is swiveled upon the pole 1 and supports the swingletrees 10 and chains or other flexible connections 11 are connected to the double tree near the ends thereof and to the irons 7 as shown in the drawings. In order to further brace the pole with relation to the arch, brace rods 12 are secured at their forward ends to the opposite sides of the pole and at their rear Specification of Letters Patent;

endsare secured by means ofbolts 13 to the forward side of the arch 3 preferably substantially at the ends of the T-iron 6. The .60

brace rods 12, of course, converge in a for ward direction, and they are preferably substantially parallel to the corresponding irons 7 1 As before stated, fracture of the arch usually occurs at the bends 4 therein and in order to prevent such fracture and further to assist the brace rods 12 in rendering the pole support more substantial, rigid and durable, other brace rods 14 are provided and these rods are secured at their forward ends to the rear side of the arch 3 by the bolts 13 which secure the rear ends of'the rods 12 to the said arch. The rods 14 diverge rearwardly and are secured at their rear ends by means of bolts 15 to the rear ends of the portions 5 of the arch, the bolts 15 passing also through the rear portions of the irons 7 It will be observed that the braces 14 extend diagonally with relation to the angle between the forward side of the arch and the end portions 5 thereof and that consequently when a forward pull. is exerted upon the forward or mid portion of the arch, the braces 14 will arrest any tendency toward straightening of the bends 4 which would be likely to result in fracture of the arch at these points. In like manner when the team is backed and rearward pressure is exerted against the forward or mid portion of the.

arch, the braces 14 prevent further bending of the arch at the sides thereof which also would be likely to result in fracture at the bends 4. It will be observed that the braces 12 and 14 at the opposite sides of the middle of the structure are substantially in aline ment and therefore, any rearward thrust or forward pull upon the pole will be transmitted substantially along the lines of extent of the said bracesand the arch itself will be relieved of strain to which it would otherwise be subjected.

Having thus described the invention, what is claimed as new is:

porting arch, said arch having an intermediate portion and lateral bowed portions ex- 7 tending rearwardly, of braces secured at their rear ends to the inner faces of the said bowed portions at the rear ends of the latter,.the braces extending diagonally within the angle between the said bowed portions and the intermediate portion of the arch and disposed at their forward ends against the rear face of the said intermediate portion of the arch at opposite sides of the middle thereof, other braces secured at their forward ends to the opposite side faces of the pole and extending rearwardly along diverging lines with their rear ends disposed against the forward face of the said intermediate portion of the arch at points opposite the forward ends of the corresponding 10 braces of each set being substantially in 15 alinement.

In testimony whereof I affix my signature.
